To get the API key for Distance Matrix API (also called an access token), you need to leave a request on the page https://distancematrix.ai/contact.
After sending the application, the user automatically receives an email with a token and information for starting. The letter also contains such information as a link to the admin panel
, links to useful pages and instructions, information about restrictions, etc.
Please note that if your project requires several keys, you can request their creation from the manager in the correspondence.
